How to Make It
Rinse the lentils. Place the red lentils in a fine mesh strainer and rinse under cold water until the water runs mostly clear.
Prep the aromatics. Dice the onion, mince the garlic, and grate the ginger. Peel and dice the carrots into small cubes so they cook evenly.

Add the tomato paste. Stir in the tomato paste and cook for 1 minute to caramelize slightly.
Build the soup. Add carrots, rinsed lentils, crushed tomatoes, vegetable broth, and the bay leaf. Stir and bring to a gentle boil.
Simmer. Reduce heat to a steady simmer. Cook uncovered for 15–20 minutes, stirring occasionally, until lentils are tender and the soup has thickened.
Finish with coconut milk. Stir in the coconut milk and simmer 3–5 more minutes. Taste and adjust seasoning with salt and pepper.

Pitfalls to Watch Out For
Overcooking the spices If the spices burn, the soup will taste bitter. Keep the heat moderate and stir constantly during the bloom.
Skipping the rinse Unrinsed lentils can make the soup foamy and murky.
Boiling too hard A rapid boil can break down the lentils unevenly. Simmer gently for a creamy but structured texture.
Under-salting Coconut milk and tomatoes need enough salt to shine. Taste at the end and adjust gradually.

Instructions
- Rinse the red lentils in a fine mesh strainer under cold water until the water runs mostly clear. This helps reduce foam and improves texture.
- Dice the onion, mince the garlic, grate the ginger, and dice the carrots into small cubes so they cook evenly.
- Heat oil in a large pot over medium heat. Add the onion and a pinch of salt. Cook for 4–5 minutes until softened. Stir in the garlic and ginger for 30 seconds, then add the curry powder, cumin, coriander, turmeric, and cayenne if using. Stir for 30–60 seconds until fragrant.

FAQ
Do I have to use coconut milk?
Not at all! In fact, Larissa doesn’t care for coconut so we don’t use it. You can use cashew cream, almond milk, or even a splash of oat milk for creaminess. For a lighter version, skip the milk and add an extra cup of broth. The soup will still be delicious, just less creamy.
Can I use green or brown lentils instead?
You can, but the texture changes. Green and brown lentils take longer to cook and hold their shape more. If you swap them in, simmer for 30–40 minutes and add extra broth as needed.
How spicy is this soup?
It’s mild to medium, depending on your curry powder and whether you add cayenne. For no heat, skip the cayenne and choose a mild curry powder. For more heat (like I like!), add chili flakes, fresh chili, or a drizzle of chili oil at the end.
What can I serve with it?
Naan, crusty bread, or rice are all great. A simple cucumber salad with lime and salt adds a cool, crunchy side. If you want more protein, top with toasted pumpkin seeds or crispy tofu.
Can I make it in an Instant Pot?
Yes. Sauté the onion, garlic, and ginger; bloom the spices; add remaining ingredients except coconut milk and greens. Pressure cook on High for 5 minutes, natural release 10 minutes, then stir in coconut milk, lime, and greens.
How do I prevent the soup from splitting?
Stir in coconut milk after the lentils are tender and the heat is low. Avoid boiling hard once the coconut milk is added. This keeps the texture smooth and creamy.
Is this soup good for meal prep?
Absolutely. It stores well, reheats beautifully, and thickens over time. Add a splash of water when reheating to reach your preferred consistency.
